Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Inspect Spark Plugs

Remove the spark plug wire or ignition coil from each cylinder.
Use a spark plug socket to remove the spark plugs.
Inspect each spark plug for wear, carbon buildup, or damage.
Replace any faulty spark plugs with OEM or equivalent parts.
Torque the new spark plugs to the manufacturer’s specifications (usually around 20-25 Nm).

3. Check Ignition Coils

If faulty spark plugs are not the issue, inspect ignition coils.
Disconnect the wiring harness from each ignition coil.
Remove the ignition coils using a socket set.
Test each coil for resistance with a multimeter (consult manufacturer specifications).
Replace any defective ignition coils.

4. Inspect Fuel System

Check the fuel pressure using a fuel pressure gauge; ensure it meets manufacturer specifications.
If low, inspect the fuel pump and filter for blockages or failure.
Clean or replace fuel injectors if they show signs of clogging or malfunction.

5. Reconnect and Test

Reconnect all components and wiring.
Reconnect the battery.
Start the engine and check for any warning lights.
